Abstract

The invention discloses a progressive electric power spot market operation efficiency measurement method and system. The method comprises the following steps: firstly, selecting an input index and anoutput index of a DEA model; secondly, constructing a primary data envelope analysis model of the DMU in a time period t by utilizing a formula; constructing a secondary data envelope analysis model of the DMU in a time period t + 1 according to the primary data envelope analysis model and the relationship between the index variation and the market operation efficiency; and converting the secondary data envelope analysis model to obtain a linear programming model, and finally calculating the operation efficiency of the power spot market in different time scales according to the linear programming model. The system comprises an index selection module, a primary data envelope analysis model construction module, a secondary data envelope analysis model construction module, a conversion moduleand an operation efficiency calculation module. Through the method, the fluctuation characteristics of the data can be effectively reflected, and the calculation efficiency and the accuracy of the calculation result are greatly improved.

Description

technical field [0001] This application relates to the technical field of power market operation management, in particular to a method and system for measuring the operational efficiency of a progressive power spot market. Background technique [0002] In the field of power market operation and management technology, my country has formed a relatively complete medium and long-term power trading mechanism and trading market. With the development of power technology, the spot market has gradually become one of the key components of the power market. How to evaluate the operational efficiency of the spot market in the electricity market is an important technical issue. [0003] At present, the method of evaluating the operational efficiency of the spot market is mainly to use the efficiency calculation method of the medium and long-term power trading market to calculate the operational efficiency of the spot market, which is a static calculation method. Specifically, firstly, ...
